Daun kemuning (Murraya paniculata L.Jack) secara empiris banyak digunakan  sebagai antibakteri, anti inflamasi, penurun kadar kolesterol darah dan juga sebagai antioksidan. Tujuan penelitian adalah menguji aktivitas antioksidan, antikolesterol secara in vitro dan menguji toksisitas secara BSLT menggunakan ekstrak etanol daun kemuning. Daun kemuning diekstraksi menggunakan etanol 96% secara maserasi kinetik, selanjutnya ekstrak yang diperoleh dilakukan skrining fitokimia, diuji aktivitas antioksidannya menggunakan metode peredaman radikal bebas DPPH, uji antikolesterol menggunakan metode Liebermann-Burchard dan uji toksisitas menggunakan metode Brine Shrimp Lethality Test. Hasil  skrining fitokimia menunjukkan bahwa ekstrak daun kemuning mengandung flavonoid, saponin, tanin, steroid/triterpenoid, minyak atsiri dan kumarin. Hasil uji aktivitas antioksidan ekstrak etanol daun kemuning diperoleh nilai IC50 sebesar 18,56 µg/mL, hasil uji aktivitas antikolesterol dengan nilai IC50 sebesar 593,95 µg/mL dan uji toksisitas dengan nilai LC50 sebesar 149,52 µg/mL. Berdasarkan hasil penelitian menunjukkan bahwa daun kemuning mempunyai aktivitas antioksidan yang sangat kuat dan dapat dimanfaatkan sebagai obat herbal.

The study reports the in vivo antidiarrheal and in vitro anthelmintic, cytotoxic, and thrombolytic activity of methanol extract of Hedychium coccineum rhizomes (MEHC). The antidiarrheal activity was determined using Castor oil-induced diarrhea and Gastrointestinal motility test in mice at the doses of 200 and 400 mg/kg body weight, whereas an aquarium worm, Tubifex tubifex, was used to determine the anthelmintic activity. The cytotoxic and thrombolytic activity of MEHC was performed by Brine shrimp lethality bioassay and clot lysis method respectively. In antidiarrheal, castor oil-induced diarrhea and gastrointestinal motility exhibited a significant reduction in diarrhea and defecation and an extremely significant inhibition in intestinal motility and peristalsis index by 200 and 400 mg/kg of MEHC. The MEHC (5, 10, and 20 mg/mL) showed a significant dose-dependent manner paralysis time and times to death in multiple comparisons to the different levamisole concentrations (0.5, 0.8, and 1 mg/mL) at in vitro anthelmintic activity. The brine shrimp lethality bioassay exhibited a weak LC50 (681.95 µg/mL; R² = 0.951) while in thrombolytic a significant percentage of clot lysis (32.70%, P < 0.05) demonstrated. The findings demonstrate that H. coccineum rhizomes could be potential sources for biological activity.

Bangladesh possesses a rich flora of medicinal plant. Out of the estimated 5000 species of phanerogams and pteridophytes growing in this country, more than a thousand are regarded as having medicinal properties. The aim of this study was to evaluate the in vitro antimicrobial activity and brine shrimp lethality of the whole plant extracts of Spilanthes paniculata, a plant belonging to the family Asteraceae. The crude extract, n-Hexane, chloroform and ethyl acetate soluble fraction of crude extract showed significant to moderate antimicrobial activity against three Gram positive and three Gram negative microorganisms. The zones of inhibition produced by the crude extract (methanolic extract), n-hexane, choloform and ethyl acetate soluble fractions were found to be 14.89 mm-19.40 mm, 14 mm-19.40 mm, 10.66 mm-13.50 mm and 9.50 mm-13.26 mm, consecutively at a concentration of 30 µg/disc. N-Hexane, chloroform and ethyl acetate soluble fractions of methanolic extract of Spilanthes paniculata were screened for antitumor properties using brine shrimp lethality bioassay. From the results of the brine shrimp lethality bioassay, it can be well predicted that n-hexane, chloroform and ethyl acetate soluble fractions of methanolic extract possess mild cytotoxicity on shrimp naupalii. The median lethal concentration (LC50, the concentration at which 50% mortality of brine shrimp nauplii occurred) of n-hexane, chloroform and ethyl acetate were 48.978 mg/ml, 92.61 mg/ml and 216.770 mg/ml, respectively, comparison with positive control vincristine sulphate with 0.839 mg/ml.

This investigation is made upon the plant Cuscuta reflexa, the flowers of it, to find out its Cytotoxicity property. The anti-oxidant property of this plant part was investigated using methanol extraction. Methanolic extract of Cuscuta reflexa.Was used to evaluate its cytotoxicity in Brine shrimp lethality bioassay where vincristine sulphate was used as standard drug. In Brine shrimp lethality bioassay, LC50 value of the extract was 36.72?g/ml and vincristine sulphate served as the positive control showed LC50 value 10.51?g/ml. So, compared to vincristine sulphate, it is evident that the methanol extract of flowers of Cuscuta reflexa was cytotoxic. In case of anti-oxidant the scavenging power (IC50) of DPPH radical was 29.26, 17.07, 18.29, 19.55 and 54.87?g/ml respectively.Asian J. Med. Biol. Res. June 2015, 1(2): 285-291

AbstractThe current research aimed to evaluate in vitro biological activities of green-synthesized silver nanoparticles using the Allium sativum clove extract. The stability of green-synthesized silver nanoparticles was evaluated via storage at 4°C, room temperature (37°C), and calcined at 300°C, 500°C, and 700°C. The antibacterial effect was evaluated using agar well, spread plate, biofilm reduction, and cell proliferation inhibition assays. The cytotoxic and antidiabetic effects were determined via brine shrimp lethality, protein kinase inhibition, and α-amylase inhibition assays. DPPH scavenging, iron-chelating, anticoagulant, and hemolytic effects were evaluated. The highest inhibition of Klebsiella pneumoniae was observed when freshly prepared, calcined (300°C), and stored nanoparticles (4°C and 37°C) were applied (9.66, 9.55, 7.33, and 6.65 mm) against freshly prepared and calcined at 700°C which showed the highest inhibition of Pseudomonas aeruginosa (8.55 and 7.66 mm). Cell viability assay, biofilm reduction assay, and spread plate method showed a significant antibacterial effect of freshly prepared silver nanoparticles. Freshly prepared and calcined nanoparticles at 300°C and 500°C possessed strong antioxidant and iron-chelating activity. Among all the synthesized silver nanoparticles, freshly prepared and calcined nanoparticles (300°C and 500°C) increases the prothrombin time. Silver nanoparticles possessed significant anticoagulant properties and less toxic at least concentration toward human RBCs. In brine shrimp lethality assay, freshly prepared nanoparticles showed a stronger toxic effect and caused high mortality of larvae. Protein kinase inhibition assay revealed that freshly prepared nanoparticles had the highest zone of inhibition (18.0 mm) at 50 µg/disc. Green-synthesized nanoparticles would be used as potential therapeutic agents to overcome both infectious and noninfectious diseases.

Jatropha Multifida

Jatropha multifida L. (jarak tintir) was a shrub, annual, and had ± 2 m high. Empirically jarak tintir sap was used as traditional medicine by Indonesian people for a long time. Only limited studies were conducted regarding its chemical compound. It was reported that multifidone (diterpenoid compound from the stem) had an activity against cancer cells in vitro. This study aimed to test the toxicity of various extracts (n-hexane, ethyl acetate, and methanol) with Brine Shrimp Lethality Test (BSLT) of Jatropha multifida L. stem. A Fraxidin (8-hidroxy-6,7-dimethoxy coumarin) has been isolated from ethyl acetate fraction based on highest cytotoxic with LC50 value 3.69 µg/mL. The isolated compound was elucidated to gain chemical structure base on spectroscopic data (UV-Vis Spectrofotometric, IR Spectrofotometric, and NMR). Toxicity of fraxidin was tested on BSLT and showed no potential activity with LC50 value > 500 μg/mL.
